SAFETY-PIN.

Sipecification of Letters Patent.

Application filed March 5. 1907- Serial No. 360,659.

i the following is a specification.

v the tongues.

This invention relates to safety pins andv has for its object to provide a comparatively simple and inexpenslve pin of this character the piercing member of which may be swung laterally to open position on either side of the guard or shield.

A further object of the invention is to provide a safety pin having spaced diverging spring locking tongues disposed on op osite sldes of the guard and serving to lock the point of the piercing member against accidental displacement when the latter is inclosed osition.

A. sti I further object of the invention is to generally improve this class of devices so as to increase t eir utility, durability and efficiency as well as to reduce the cost 'of manufacture. v

Further objects and" advantageswill appear in the following description, it being understood that various changes inform,

proportions and minor details of construction may be resorted to within the scope of the ap ended claims.

Fig. 10 is a side elevationillustrating a further moilificatiiin.

Fig. 11 is a transverse sectional view taken on the line 11-11 of Fig. 10.

Similar numerals of reference indicate corresponding parts in all of the figures 'of the drawings.

- The body portion of the pin forming the sub ect ,matter of the present invention is preferably formed of a single piece of wire or other suitable material having an intermediate portion thereof bent to produce a s ring coil 5 and its opposite ends extended aterall to form relativelystationarv and movab e members 6 and 7 one of which. is pro- Vided with a piercing point, as indicated by dotted lines at 8 in Fig. 1 of the drawing.

Rigidly secured to the relativel stationary member 6 of the pin is a guar or shield 9 preferably stamped or otherwise formed from a single-piece of sheet metal having its opposite longitudinal edges at one end there of out to form a tubular member or socket 1.0 for the reception of the relatively station ary member 6, the longitudinal ed es of the guard at the opposite end thereof eing extended upwardly in spaced parallel relation to form a keeper 11 for the reception of the piercing point 8.

The intermediate, portion of the guard 9 is, curved or rounded and bent inwardly to prevent a smooth unobstructed surface thereby to prevent tearing or otherwise injuring the garment when using the pin in the ordinary manner.

Rigidly secured to the stationary member 6 is a spring locking member, having an intermediate tubular portion or socket 12 adapted to receive the member 6 and provided with diverging arms 13 and 14 which extend to points adjacent the opposite lon gitudinal edges of the keeper 11 thereby to patented. Dec. 3 1 fine?" by pressing or bending the adjacent edges of the guard inwardly, as will be readily understood.

"In order to lock the piercing member shown in Fig. 1 of the drawing it is merely necessary to. press inwardly and laterally on the same which will depress the adjacent spring locking tongue and thus permit the iercing -member 7 to seat itself in the ee or 11.

y forcing the spring tongues 13 and 14 together a space wi 1 be formed betweenthe spring tongues'and the adjacent upper edges of the keeper sufficient in Width to permit the passage of the piercing oint thus allowing the latter to be readily disengaged from the keeper.

It will thus be seen that the piercing members may be moved to open or closed position from either side of the guard and that when the piercing member is in closed position the s ring tongues 13 and 14 will effectually lock t e iercing point of the member 7 against acci ental displacement.

In Figs. 5 to 7 inclusive of the drawings, there is illustrated a modified form of safety pin which can be opened only from one side of the guard or shield. In this form of the device one side of the guard or shield 9-is imperforate while the opposite side thereof ,is open and the adjacent edge of the metal 'formin the shield is bent upwardly in substantia 1y parallel relation to the imperforate wall of the shield to form a keeper 11.

The locking tongue 17 in this form of the device is formed with a segmental extension 18 which bears against the imperforate' face of the guard and is locked in engagement therewith by contact with the inwardly turned edge 19 of said guard. The upper edge of the plate forming the locking member 17 is rovided with an over-hanging hook 2O WhlClI embraces the stationary member 6 and serves as an additional suppcrt for the M spr ng locking member.

In Figs. 8 and 9 of the drawing there is illustrated a further modification in which the spring lam-king tongues 21 and 22 are formed integral with the guard or shield, the l l piece ofnietal bent to form a tubular portion 1 for the reception of the stationary portion construction being otherwise similar to that shown in Fig. 1 of the drawings.

empee ,or shield is open on one side and provided at its opposite side with an imperforate wall,

the tongue 23 being preferably formed intethese tongues may be made of spring metal so as to yield when lateral pressure is applied thereto.

The safety pins may be made in different sizes and shapes and nickeled, plated or otherwise coated to give the same a neat attractive appearance.

Having thus described the invention what is claimed is:

1. A safety pin including relatively'stationary and movable members one of which is'provided-with a piercing point, a guard secured to the stationary member and provided with a keeper for the reception of the piercing point, and a spring locking tongue carried by one end of the guard and having its free end spaced from and disposed in alinement with the adjacent longitudinal edge of the keeper.

2. A safety pin including relatively stationary and movable members oneof which is provided with a piercing point, a guard secured to the stationary member and having its free end bent to form a 'kee er for the reception of the piercing point, ocking tongues depending from the fixed end of the guard and connected by an integral tubular member for the reception of the stationary,

member, the free ends of the tongues being deflected laterally and disposed in alinement with the adjacent longitudinal edges of the kee er.

3. A sa ety pin including relatively stationary and movable members one of which is provided with a piercing point, a guard rigidly secured to the stationary member and having its opposite end bent to form a keeper, a tubular member interposed between the stationary member and guard, and diverging spring locking tongues deending from the tubular member and having their free ends s aced from and disposed in alinement with the'adjacent longitudinal edges of'the keeper.

'4. A safety pin-including relatively stationary and movab e members one of which is provided with a piercing point, a'guard secured to the stationary member-and having its'free end bent to form a keeper, a"

spring locking member formed of a single w l Figs. 10 and U of the drawings illustrate of the pin and provided with de ending a further modification in which the piercing l spring locking tongues of less width t an the member is free to more in one direction tubular member and disposed one on each 125 only.
